To all whom it may} concern:

Be it known that I, CHARLES IIAROLD VAITHMAN, a subject of the King of Great Britain and Ireland, residing at 70 Guildiord street, London, England, have invented a new Advertisement Device, (for which I have filed an application. in (ii-eat Britain, October-l9, Patent No. 21,196,) of which the following is a specification.

This invention has reference to advertisement devices of the kind in which the vibrations or oscillatory movement of a. vehicle or vesselv are utilized to swing a pendulum or the like the movements of which are transmitted through appropriate gearing to a a band or disk bearing advertisements which are caused to appear before an opening in the casing containing the apparatus.

The invention comprises the particular arrangement and combination of parts all hereinafter more particularly described and finally pointed out in the claims.

In the accompanying drawings:

Figure 1 is a front elevation of the de- Fig. 2 isa fragmentary elevation to an enlarged scale "with the casing broken a "ay, Fig. 3 is a plan view of Fi Fig.4 is a detail of a modification, and Fig. 5 is a vertical section through Fig. 4:. Fig. 6 a perspective view of the device of Fig. 1, parts of the casing being removed,

and Fig. 7 isa view of a detail of the brackets for a pair of rollers.

Referring now to the drawings, 1 indicates the hinged front of acasing 2 provided with panels or glazed openings 2) and 4. Mountedupon the back of the casing 2, is a 1 plate 5, having flanges 6 and 7 in which are mounted bearings 8 and 9 for the driving rollers 10 and 1,1. The ends of the roll (FPS-Which. are not shown in Fig. 2+are supported in suitable bearing brackets 35, 36 secured to the casing 2. Beneath the 5 another plate 12 issecured to the backoif the casing and this plate also is flanged. at 13 and 14 to support in slots 37, 38 the guide rollers 15 and 16 approximately the same length as therollers 10 and 11, and supported at the ends, notshown in Fig. 2, by suitable brackets 39, 40.

Mounted in the plate 5 is a spindle 17 carrying a wheel 18 provided with bevel teeth on its surface and a second set of teeth on the periphery. \Vheel 1S meshes with pin ions 19 and 20 located respectively on the axes of the rollers 10 and 11.

Rotation of the wheel 18 in either direction rotates the rollers 10 and 11 in opposite directions.

In order to rotate the wheel 18 a pendulum rod 21 carrying a weight 22 is loosely mounted on the spindle 17 and the rod ex tends above the axis 17 as shown. A pawl 22 mounted on the pendulum rod is normally held in en agement with the teeth on the periphery ot wheel 18 by means of a spring 21. Another pawl mounted on plate 5 also engages the same teeth and is held in contact therewith by a spring not shown. As the pendulum is locked the pawl 23 rotates wheel 18 through a small angle while the pawl 25 slips over the teeth on the periphery. On the return stroke of the pendulum the pawl 25 locks the wheel 18, thereby preventing backward rotation and at the same time pawl 23 slips over the teeth.

It the device is mounted on a vehicle or vessel in motion the pendulum will oscillate and so impart motion in one direction to the wheel 18 and thereby cause the rollers 10 and 11 to rotate in opposite directions.

Buffers 26 and 27 on the pendulum bob obviate any shock due to excessive motion of the pendulum.

About each set of rollers 10, 11, 15, and 16 endless bands of flexible material 28 and 29 respectively are trained. These bands pass across the openings or panels 3 and 4-. in the casing and move in opposite directions as indicated by the arrows in Fig. 1. Upon each band a series of notices, advertisements, signs, symbols or other devices may be mounted, and in operation these bands will move intermittently across the openings or panels so as to display the whole series of advertisements, etc, in succession.

As an alternative to the above described arrangement a compound ratchet device may be employed in which case the spindle 17 is formed in two co-axial parts and the pendulum instead oi: being tree to swing on the spindle 17 as in Figs. 2 and 3 is keyed or otherwise secured to one portion of the two part spindle.

In the arrangement shown in Figs. 4 and 5 the pendulum rod 21 is keyed or otherwise secured to the spindle 17 which latter is supported by means of avbracket 5 and washer 30 held in place by a collet 31. In this case the pawl 23, carried by the pendulum is located beneath the pivoted point of the pendulum and the pawl 25 consists of a simple spring secured to the flange 32 of bracket 5 at 33. In this case instead of the teeth being cut on the periphery of wheel 18 a separate toothed wheel 3% is mounted on the boss of the'wlieel 18. This construction is simpler and occupies less space than the arrangement described in connection with Figs. 2 and 3. e

In some cases, where it is desirable to increase the length of the band 2-8 or 29, additional guide rollers are located for instance between the rollers 10 and 15. The

band is trained around these additional rollers in-the space between rollers 10 and 15.

Normally the guide rollers715, 16 are supported by the band 28 or 29 respectively and their axes rotate in vertical slots 37, 4:1 and 38, 42, respectively; In this way the weight of each guide roller keeps the band taut, but is free to rotate.

The bearings for the rollers 10 and 11 are shown as adjustable that is to say for the purpose of removing the rollers to place or replace the band in position, and the bearings for the rollers 15 and 16 are also shown as adjustable, that is to say one of each is "slotted horizontally for the purposeof removing the rollers and both are slotted vertically for keeping the bands taut by the weight of the roller suspended thereby and forthe purpose of taking up any slack which might in time appear in the bands from various causes. Suitable catches, as 43, M are provided forlocking the rollers to their bearings at one end.

' Such a device 'as described above may be mounted in vehicles subjected to variations in velocity or to vehicles or vessels subject to continual or intermittentvibration or rock ing motion, and in all cases the bands carrying the advertisement will be moved continuously or intermittently. Instead of using bands, such as 28 and 29, the rollers 10, 11, 15 and 16 may be replaced by short axles or cranks carrying disks, on the surface of which the signs or advertisements I are placed and are moved across openings or panels in a suitably modified casing.

I claim. 1. In' an advertising device, the comblnation with a frame adapted to be mounted on a vehicle, of a pendulum, a pivot therefor, a ratchet wheel, and a gear wheel driven thereby. mounted on said pivot, a pawl on the frame, a pawl on the pendulum,

said pawls engaging said ratchet wheel, rollers having their axes disposed in a plane substantially parallel to the plane in which the pendulum swings, a pinion carried by one of said rollers and meshing with said gear wheel and a visible surface adapted to be moved by said driven roller.

2.
